The addition of anti-skinning agents to paint prevents the formation of skin, which is formed due to oxidation and polymerization of the binder at the paint-air interface. The anti-skinning agents inhibit or delay the oxidative processes, which lead to skin formation during both storage and application. They do not affect the color and film formation tendencies. The formation of skin is directly proportional to the temperature of the environment the paint is exposed to, and the solid content in the paint. Poor formulation, production faults and faults in processing also contribute to this problem. Also, the skin formed blocks the nozzles of the spray painting equipment and impair the appearance of the coat. The loss occurred due to skinning is estimated at 3-5%.
Prevention Measures include proper sealing of paint pails, anti-skinning agents, straining paint through a nylon strainer, storage of paint in cool areas and replacing air by nitrogen in headspace of storage containers. The only disadvantage of using anti-skinning agents is the increase in drying time due to anti-oxidant property. Dosage should be carefully optimized to attain right level of anti-skinning activity and drying time.
Anti-Skinning Agents Market Taxonomy
On basis of type of agent used
On basis of Application
On basis of End User
Anti-skinning agents are generally used as solvent borne coating, mainly in alkyd based paints. The increasing use of methylethylketoxime (MEKO) skinning agent in alkyd based paints used for printing inks, industrial wood, pigment dispersions, and general industrial end-uses to prevent skinning factor are fueling the growth of global anti-skinning agents market. Moreover, oximes and phenols are well-known as oxygen scavengers and largely helps in reducing oxidation rates. Hence, they are the primary constituent in most anti-skinning agents. MEKO is the most widely used anti-skinning agent and is added in very small proportions to the paint (0.5%). Retention aids prevent applied paint films from drying too quickly. Furthermore, solvents used as anti-skinning agents dissolves the components which form skins.
The growing demand for anti-skinning agents from printing inks industry is the major driver for the growth of anti-skinning market globally. The decorative end-use segment is the fastest growing segment in the anti-skinning agent market. The factors such as the growing GDP and rapid urbanization in Asia Pacific, primarily in China, and India creates a highly conducive environment for market growth. Due to which, the demand for new and improved infrastructure is increasing, enabling the growth of decorative paints, which in turn is fueling the anti-skinning agents market during the forecast period.
Surging demand in Asia-Pacific Augmenting Market Growth
Major companies are adopting various organic and inorganic growth strategies to sustain a better market position in the anti-skinning agent market. For instance, the company named Brochers has developed an oxime-free anti-skinning agent, which have anti-oxidant properties similar to oximes and phenols, and are non-hazardous substitutions for them. Oximes provide a major advantage of being oxygen scavengers are also toxic in nature. Some of the major companies operating in the Anti-Skinning Agents market are Borchers, Dura Chemicals, Gelest Inc., OMG Americas, Polyrheo Inc., GSFC Ltd., Arkema, and Troy Corporation.
